The Glossary
A bench has a vocabulary. Each word is given once, in the sense the desk uses it, with the page that puts it to work.
A word on this site means what this page says it means, and the desk tries not to need a second sense for it. Each term is given once, in the sense the register uses, with the page that puts it to work. Where a term is used in the trade with more than one meaning, the desk says which one it has dropped.
Air release adhesive
A pressure sensitive adhesive and a film face embossed with a microscopic channel pattern, so that air trapped under the film as it is laid can escape outward instead of staying as a bubble. The catalogue of 2019 named it on every product sheet it left on the record.
Calendered
Made by pressing a warmed vinyl compound between rollers. Stiffer than cast film at the same thickness, cheaper by area, and the route for the thicker gauges. The trade's bumper sticker stock is calendered, which is why the 2019 home page used the phrase as shorthand for the thick alternative.
Cast
Made by spreading the compound as a liquid onto a carrier and drying it. No roller memory, flatter, and the route that reaches the thin gauges. The catalogue claimed its wraps were cast as well as 2 mil, and that half of the sentence is manufacture, not arithmetic.
Colorway
One design printed in more than one color scheme. A colorway changes contrast, not geometry: the same figure in white and in gray is two colorways of one pattern. Read in the hex line and colorways.
Coverage
How much of the shaft's length a band covers, read forward from the nock throat so that two arrows of a set can be compared. Not a coat: the point end and the fletching zone stay bare. Read in shaft coverage.
Cresting
The decorated band on the tube, and the region of the shaft where it sits. Traditionally paint, laid by hand; on this register, printed film. A wrap is cresting that comes off again.
Front of center
The distance the balance point sits ahead of the arrow's midpoint, as a percentage of arrow length. Added mass at the tail lowers it, and the desk's arithmetic puts the change from a wrap at a few tenths of a percent. Worked in added tail weight.
Grain
The mass unit of archery: 0.0648 grams, a 7000th of a pound. Film mass converts into grains because grains are the unit in which arrow mass is matched and discussed.
Gauge
The thickness of a film. On this register, quoted in mil, and the two gauges on the record are 2 mil and 4 mil.
Hex line
The geometric family of the catalogue: a hexagonal figure repeated across the band, printed in single colors. Read in the hex line and colorways.
Mil
One thousandth of an inch, 25.4 micrometers. The trade unit of film thickness. A 2 mil film is 50.8 micrometers, which is the range of a human hair.
Nock throat
The groove where the string seats, and the fixed landmark from which the desk reads coverage, because it sits in the same place on every arrow of a set.
Overlap
The part of the strip that rides over the first edge and closes the wrap. Its length is the strip width minus the tube's circumference, and it is a seam decision rather than a balance one. Read in cut lines and overlap.
Pressure sensitive adhesive
An adhesive that bonds under thumb pressure at room temperature, and softens again under heat. The second property is what makes a wrap removable.
Release liner
The coated backing that the adhesive face of a wrap is peeled from. It comes off before the film goes on and has no further job.
Seam
The line where the two long edges of the strip cross on the tube. Every wrap has one. What the crossing does to the print is read in cut lines and overlap.
Spine
The stiffness of a shaft, measured by supporting it and hanging a weight at its middle. A wrap adds no static spine, because it adds no stiffness to the wall of the tube.
State line
The family of the catalogue that carried the designs of thirty one states, coded by state abbreviation. Read in the state design tradition.
Wrap
A rectangle of printed, adhesive coated vinyl film, cut to close around a shaft, applied to the cresting area, and removed with heat. On this register it is a piece of equipment to be measured, and never a product on sale.
The numbers behind these words are in the spec table, and the rule the desk follows when a word or a figure has to change is on editorial standards.
